(CNN) - In a move with both 2014 and 2016 implications, Texas Gov. Rick Perry will weigh in Tuesday on the U.S. Senate battle in New Hampshire.

The longtime Republican governor from Texas will team up NHGOP Chair Jennifer Horn on a media conference call to criticize both Democratic Sen. Jeanne Shaheen and President Barack Obama over the current border crisis.

Washington (CNN) – If lawmakers delay taking action now on climate change it could cost taxpayers exponentially more in the future to deal with the effects of a warming planet, the White House is warning Tuesday.

A report from President Barack Obama's administration says the costs of mitigating carbon emissions will rise 40% per decade unless something is done now to stem the outpouring of pollutants scientists say are causing global warning.

Washington (CNN) – During an awards ceremony at the White House, President Barack Obama whispered in the ear of superstar musician Linda Ronstadt that he once had a crush on her.

The President admitted to the crowd afterwards that, "I told Linda Ronstadt I had a crush on her back in the day " Ronstadt joined Obama on stage, along with 11 other recipients of the 2013 National Medal of Arts.

Washington (CNN) – With some communities across the nation fighting attempts to house some of the unaccompanied Central American kids detained at the border, President Obama got a dose of welcome news from one of his closest political allies. Chicago Mayor Rahm Emanuel's administration says it is willing to house up to 1,000 children in city facilities.

“The influx of unaccompanied child migrants is a growing humanitarian crisis that we can no longer ignore,” Emanuel said Sunday in a statement. “While we have our own challenges at home, we cannot turn our backs on children that are fleeing dangerous conditions. We will do our part to ensure that these children are given access to services and treated fairly and humanely.”

Washington (CNN) – If you wanted a friend to defend your reputation against serious sideswipes, who better to do it than one of the most recognizable women in the world, with years of experience beating back barbs?

Enter Hillary Clinton in defense of President Barack Obama. As conservatives throw arrows aimed at the President's handling of multiple world crises, Clinton defended her former adversary-turned-boss-turned-friend.

The former secretary of state – and prospective presidential candidate - sat down with CNN's Fareed Zakaria for a wide-ranging interview taped Friday and aired Sunday on "CNN's Fareed Zakaria GPS."

Some conservatives accuse Obama of not being tough enough on Russian President Vladimir Putin. Is the President appropriately handling the Ukranian crisis, Clinton was asked?

(CNN) - Russian President Vladimir Putin bears at least some responsibility for the shooting down of Malaysia Airlines Flight MH17, former U.S. Secretary of State Hillary Clinton said Friday.

"I think if there were any doubt it should be gone by now, that Vladimir Putin, certainly indirectly - through his support of the insurgents in eastern Ukraine and the supply of advanced weapons and, frankly, the presence of Russian Special Forces and intelligence agents - bears responsibility for what happened," she told CNN's Fareed Zakaria in an exclusive interview that will air Sunday.

Clinton's comments come just over a week since Flight MH17 crashed in eastern Ukraine, killing all 298 on board. Pro-Russian militants have been accused of downing the plane using Russia-supplied armaments and of interfering with the subsequent investigation at the crash site.

U.S. President Barack Obama last week called the crash a "wake-up call for Europe and the world that there are consequences to an escalating conflict in eastern Ukraine," a view Clinton echoed in urging Europe to go further.

Washington (CNN) – Amid the push for peace in the Middle East and the push for reduced tensions between Russia and the Ukraine, how much has President Barack Obama's leadership helped mitigate those dire situations?

Two top members of Congress offered starkly different characterizations on Sunday. While one praised the President's "strong" leadership, the other accused Obama of being "AWOL," serving up "passive responses to naked aggression all over the world."

House Minority Leader Nancy Pelosi, Democrat of California, and South Carolina Republican Sen. Lindsey Graham, a member of the Armed Services Committee, offered their thoughts to CNN chief political correspondent Candy Crowley during interviews on CNN's "State of the Union."

Is it bad optics, Pelosi was asked, for the president to attend fundraisers as parts of the world seemingly blow up around him?
